Interpretive Summary: Brown ring patch, sometimes referred to as Waitea Patch, is an emerging disease of cool-season turfgrasses. It was first identified on Agrostis stolonifera in Japan in 2005 and has become a widespread disease of Poa annua in the United States since 2007. This section of the 4th edition of the Turfgrass Compendium details the symptoms, causal agent, disease cycle, and other information required to diagnose and control brown ring patch.
